craustin1: From my experience, I believe the h-20 is a better receiver than the h-10. It has great video/audio. I find the model 600 runs too hot and, at times, it presents problems. The model 100 runs much cooler and, so far, for me zero problems. I would call Directv and see if I could get it with no or little charge. I have received all my recent receivers free from Directv. They have no fixed policy on the matter. The model 600 has a great OTA section by the way and the 100 is close.
